A field experiment with conservation tillage was set up to study the effect of using cover crops: spring rye (Secale cereale) and vetch (Vicia sativa), and various methods of soil preparation prior to sowing: no-tillage, rotary disk ploughing in the spring, and pre-winter disk ploughing, on the growth and yielding of onion cv. Wolska as compared with conventional cultivation methods.Sprouting of onion plants was best on those plots where spring rye mulch had been mixed with the soil during pre-winter disk ploughing.
